We are a well-known large-scale private enterprise. We are professional in producing vacuum tubes. Our company was founded in 1986, starting business by producing electric beads. Then we developed into one of the largest professional manufacturers producing the first auto use H4 bulbs in Zhejiang, which only took us a short period of 4 years. Over these years, we have been renowned at home and abroad for products of high quality and high performance.

In 2000, we timely adjusted the industrial structure and entered into the new field, namely the sunrise industry of "solar vacuum tubes", as the new direction of sustainable development. With a high starting point and rapid development, in only five years, we have realized fission-type development, in terms of technology, equipment, processes, products and personnel. We have 20 sets of production lines. We specialize in adopting new graded coating, vacuum technology and strict control to ensure the high collection efficiency and anti-decay properties of vacuum tubes; putting up round intelligent automatic cutting equipment to ensure accurate tubes and deionized water reverse osmosis equipment and using pure water to ensure that tubes are highly cleaned. The products include general efficient tubes, three-high tubes, three-cavity tubes and other series, with length ranging from 1.2m to 2.1m and about 100 species. Our annual output can reach 7 million vacuum tubes.

We have already passed ISO9001:2000 International Certification. Product quality has been tested by Quality Supervision and Inspection Center of National Solar Water Heaters. "Pursuit of Harmony and Values" is the core concept and fundamental attribute of our brand culture. "Indomitably and Bravely Stand at the Forefront" is our spirit. In order to make us a Chinese professional quality production base of vacuum tubes, our company has strengthened research and envelopment ability and gathered a large number of industrial elites. We plan to set up 30 sets of production lines in 2 years. With annual production capacity exceeding 10 million vacuum tubes, we are striving to become a well-known brand and a famous trademark in Zhejiang, so as to become a well-known brand in the field of Chinese solar vacuum tubes. The eventual goal is "Becoming a Global Outstanding Professional Supplier of Vacuum Tubes". Solar vacuum tubes have been exported to Europe, America and dozens of other countries and regions. The products have gained users' trust.
